We would need a bit more details of what you want to do. But technically if you just want to have 2genes one after the next to insert you could either plasmids with multiple insertion sites, make your construction in those (easy) then excise the double insert and transfer it to the genomic DNA as you would do.If you want to be more clever you can use a super PCR (I highly recommend Phusion Taq) to build your sequence and promoters from wherever they are available and insert the product in your transfer structure.
